 Процент покрытия 100% (отчет: `htmlcov/index.html`)
 
-### Структура проекта
-
-- `praktikum` - пакет, содержащий код программы
-- `tests` - пакет, содержащий тесты, разделенные по классам. Например, `bun_test.py`, `burger_test.py` и т.д.
-
 ### Запуск автотестов
 
-**Установка зависимостей**
-
-> `$ pip install -r requirements.txt`
-
 **Запуск автотестов и создание HTML-отчета о покрытии**
 
->  `$ pytest --cov=praktikum --cov-report=html`
+>  `pytest --cov=Diplom_1.burger --cov-report=html --cov-report=term`
